Question

build build a machine that can automatically clean a coffee mug Bill wants the machine to be able to do an amount of work represented by the inequality x + y greater than or equal to 2 while using battery power that remains at level represented by the inequalities for x + y greater than or equal to -1 where X and Y both represent the number of minutes spent on cleaning different parts of the tank at the machine Spence 5 in three minutes on X & Y respectively does he meet those requirements?

Answer 1

We have to meet these restrictions:

Amount of work:

$x+y\ge2$

Battery power:

$x+y\ge-1$

If the values of x and y are x=5 and y=3, then we have to evaluate each restriction:

$\begin{gathered} x+y=5+3=8\ge2\longrightarrow\text{true} \\ x+y=5+3=8>-1\longrightarrow true \end{gathered}$

Answer: Yes, they meet the requirements.
